Dynamic Analysis of Diesel Engine Piston Based on Time Spectral Element Method

On the basis of traditional static finite element simulation, the paper adopts time spectral element method with higher accurate of interpolation precision to disperse the alternating mechanical load, meanwhile, applies the load results to its piston dynamic analysis to get the time history curve of piston stress and distortion. What we get from the experiment provides theoretical foundation for further study of piston fatigue analysis and life prediction.
